复合地基面积置换率的计算方法

Calculation Method of Area Replacement Ratio of Composite Foundation

摘要:

从复合地基单桩面积置换率的定义出发，计算大面积规则布桩、不规则布桩以及实体基础下的面积置换率，用简单的方法来解决实际复合地基设计、注册岩土工程师考试中的面积置换率的计算问题，较规范中的等效圆面积折算方法更符合实际、更简单、更高效。

Abstract:

tarting from the definition of single pile area replacement ratio of composite foundation, the area replacement ratio of large-area regular pile arrangement, irregular pile arrangement and solid foundation are calculated with simple method, which can be used for composite foundation design and the area replacement ratio calculation in examination of registered geotechnical engineer and is more practical, simpler and more efficient than equivalent circle area conversion method in the “Technical Code for Ground Treatment of Buildings”.
